Abstract

Spatial autocorrelation measures the spatial dependency of observations that quantifies the degree of spatial clustering or dispersion in the values of a variable measured across a set of locations. There are two types of spatial autocorrelation measures such as global measures and local measures. In this article we are giving an overview of Moran’s I and Geary’s C (Global measures) along with the steps for manual calculation and R code for the estimation of these measures.
